Are you sure your rear axle ratio is a 4.11? My 62 is a 3.90 and these were alot more common. Anyways i have a rebuilt 235 about 3500 miles on it now and i am getting 24 miles/per/gallon

I just put in a S10 5 speed tranny and i figure i will be getting close to 30 miles/per/gallon now!!

my tires are 225/70/15
